Thus, c

= 1/3, c

= (π⋅i+2)/π

, c

= (π⋅i+1)/(2π

The Fourier series with three elements will be written as

g(t) ≈ Re[(1/3) + (π⋅i+2)/π

⋅exp(i⋅π⋅t)+ (π⋅i+1)/(2π

)⋅exp(2⋅i⋅π⋅t)].

For additional definitions, applications, and exercises on solving differential

equations, using Laplace transform, and Fourier series and transforms, as well

as numerical and graphical methods, see Chapter 16 in the calculator’s user’s

guide.
